  Porcine reproductive and respiratory syndrome virus (PRRSV) is an important porcine pathogen globally. Reverse transcription-polymerase chain reaction (RT-PCR) for PRRSV detection is an important tool for disease management and control. Clinical sensitivity of RT-PCR for PRRSV detection is compromised to a certain degree by the high genetic diversity in the PRRSV genome. A duplex RT-insulated isothermal PCR (RT-iiPCR) for the North America lineage of PRRSV (PRRSV-NA) has been developed by targeting both ORF6 and ORF7 to increase test inclusivity. In this study, its limit of detection 95% was determined to be about 5 genome equivalents per reaction by testing a serial dilution of in-vitro transcribed RNA. The PRRSV-NA duplex RT-iiPCR was compared with an ORF7 real-time RT-PCR (rRT-PCR) published previously for the evaluation of analytical and clinical performance. Both tests did not re.. Read More»
